Use BoringSSL instead of mincrypt to speed up package verification.

This changes the verification code in bootable/recovery to use
BoringSSL instead of mincrypt.

Cherry-pick of 452df6d99c81c4eeee3d2c7b2171901e8b7bc54a, with
merge conflict resolution, extra logging in verifier.cpp, and
an increase in the hash chunk size from 4KiB to 1MiB.
